Daniel Dubois’ trainer has accused Oleksandr Usyk of conning the referee the first time the two heavyweights squared off.

The fight comes almost two years after their first contest, when Usyk was a unified champion having twice beaten Anthony Joshua across 12 rounds. At that point, Dubois was a little greener but did manage to get Usyk down to the canvas though it was ruled low and Usyk was given all the time he needed to recover.

Daniel Dubois' trainer tells Oleksandr Usyk he "conned the boxing world" as the two champions meet in London before this summer's undisputed title fight.
